So you've got a Galaxy S device and you want it improved. You'd like it not only to work better, but faster. Have you taken a bite of Voodoo? Once you do, you'll find that there's a Lagfix that'll replace your cruddy RFS filesystem with the Linux-standard Ext4 filesystem. What's that do? It restores your I/O performance and overall user experience to the speeds and quality it aught to be! Now, with the help of XDA member supercurio, you can have these Ext4 speed improvements with a totally safe mount option on /data! Hooray forever!
